Part II - Compliance Paths
In addition to the mandatory requirements previously noted, energy code provisions require you to choose
one of four alternative compliance paths to demonstrate code compliance. Indicate the path you choose
below by checking one of the following boxes and completing the instructions.
 Prescriptive (as prescribed by the code)
If you choose to use the prescriptive method of compliance, you may demonstrate compliance by
completing the attached Prescriptive Compliance Report Form. Sign the compliance statement below
and attach a copy of the completed Prescriptive Compliance Report Form along with this form when
submitting for a building permit. Please note that the prescriptive insulation materials and methods
shown on the building plans shall match what is indicated on the compliance report.
 Total UA Alternative (prescriptive trade-off method)
Compliance with the Total UA Alternative method may be demonstrated by completing a compliance
report using REScheck software provided free of charge at energycodes.gov. At present, REScheck
does not offer a code edition incorporating State of Michigan amendments. However, you may use
the 2015 International Energy Conservation Code (2015 IECC) since it meets or exceeds Michigan
requirements. Please use “Utica, Michigan” for location criteria. Sign the compliance statement
below and attach a copy of a signed compliance report, including the inspection checklist, with this
form when submitting for a building permit.
Please note that the building plans shall show the same materials and methods you use to complete
the REScheck form. For example, if you use basement wall insulation in REScheck, such insulation
should be clearly indicated on the building plans too.
 Simulated Performance Alternative (performance analysis)
Certain commercially available compliance software (e.g. REM/RATE, etc.) may be used to
demonstrate that the proposed construction will have an annual energy cost that is less than or equal
to the energy cost of the standard reference design. Please see Section N1105 of the code for specific
criteria.
Such software shall generate a compliance report that documents that the proposed design complies
and shall include information outlined in Section N1105. Sign the compliance statement below and
attach a copy of the completed compliance report with this form when submitting for a building
permit.
 Above Code Programs
Compliance with certain energy efficiency programs such as Energy Star Version 3 and ICC 700-2012
“silver” are acceptable. See Section N1101.7 and N1106 for specific provisions. Provide a compliance
report that documents that the proposed design meets program requirements. Sign the compliance
statement below and attach a copy of the completed compliance report with this form when
submitting for a building permit.
Part III - Compliance Statement
I have read and completed the above form and will insure that the actual construction complies with Chapter
11 of the 2015 Michigan Residential Code.

In the table below, indicate the proposed values of insulation, fenestration and other components in your
proposed home. Please note that such components shall meet or exceed the performance of the prescribed
values. If you have any clarifications, please note them in the comment section. Finally, insure that the
building plans submitted show the same materials and methods you use to complete this form.

a. R-values are minimums. U-factors are maximums.
b. The fenestration U-factor excludes skylights.
c. “10/13” means R-10 continuous insulation on the interior or exterior of the home or R-13 cavity insulation at the interior of the
basement wall.
d. “15/19” means R-15 continuous insulation on the interior or exterior of the home or R-19 cavity insulation at the interior of the
crawlspace wall. “15/19” may be met with R-13 cavity insulation on the interior of the crawlspace wall plus R-5 continuous insulation
on the interior or exterior of the home.
e. R-5 shall be added to the required slab edge R-values for heated slabs.
f. Or insulation sufficient to fill the framing cavity, R-19 minimum.
g. First value is cavity insulation, second is continuous insulation or insulated siding, so “13 + 5” means R-13 cavity insulation plus R-5
continuous insulation or insulated siding. If structural sheathing covers 40% or less of the exterior, continuous insulation R-value may
be reduced by no more than R-3 in the locations where structural sheathing is used – to maintain a consistent total sheathing thickness.
h. The second R-value applies when more than half the insulation is on the interior of the mass wall.
This form is intended to provide a simplified method of documenting prescriptive code compliance. Please see the
full code context for exceptions, alternatives and other requirements that may apply.
